Atlas Copco Air Motors

Lubrication free motors
The lube free LZL models are designed for reliable running
at very low and medium speeds. The absence of lubrication
results in a cleaner surrounding area and no contaminating
aerosols to come in contact with the driven equipment.
These motors are among other applications ideal for mixing.
To further ensure a clean and hygienic environment, a double
shaft seal is used and all components that come in contact
with the mixed medium are made of corrosion resistant
material. Thanks to a new cylinder design and highly stable
bearings, LZL require no extra drive shaft support and is
ready for mounting without add-ons. For good adaptability,
the lube free motors are available with IEC or NEMA.
Mixer motors are EX certified according to ATEX directive
Ex II 2G T5 IICD 85° C.
Data at air pressure 6.3 bar (91psi)
Stainless steel motors
Stainless steel motors are available in the size LZL 05. They
are lube free and have the same features as the other lube
free motors. All external parts including the output shaft
are made of stainless steel which make the motors very
corrosion resistant and thereby ideal is applications like food
industry, corrosive mixing applications and chemical industry.
These motors are EX certified according to ATEX directive
Ex II 2G T4 IICD 110° C.
The material used in all external parts is ISO 683/Xlll Type 17,
SS 14 2346, DIN 17440 X 12CrNiS188.
The material in the output shaft is ISO 683/Xlll Type 9b,
SS 14 2321, DIN 17440 X 22CrNi17.
